Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for non-ironing finishing of high-strength pure cotton textiles, which not only overcomes the problem of poor water solubility, but also avoids the disadvantages of ammonia water modification; The anti-wrinkle effect is good, because it is cross-linked under alkaline conditions, there is no problem of high-temperature acid degradation of cellulose, and the strength retention is high

Embodiment 1

[0017] Add 120g of FAP, 20g of sodium carbonate, and 2g of sodium hydroxide into 1L of water, heat to partially hydrolyze and completely dissolve the FAP, and use it as a finishing solution. Immerse the pure cotton fabric in the finishing solution, soak it completely, dehydrate to 70% of the liquid retention rate, dry at 80°C for 1min, then bake at 140°C for 3min, wash with water, neutralize with HAc, and pad with silicone The softener is then dried at 80°C to obtain the finished product.

Embodiment 2

[0019] Add 100g of FAP and 20g of sodium carbonate into 1L of water, heat to partially hydrolyze and completely dissolve the FAP, and use it as a finishing solution. Padding the pure cotton fabric with the finishing solution, with a liquid retention rate of 60%, steaming it for 2 minutes at 120°C and a humidity of 60%, washing it with water, neutralizing it with HAc, padding it with a silicone softener, and drying it at 80°C to obtain finished product.

Abstract

The invention relates to a noniron finishing method for purified cotton textiles with high strength retention, which comprises the following steps of: padding the purified cotton textiles by using finishing liquid with the liquid rate being 40-80%, then baking, and finally, neutralizing, washing and softening, wherein a preparation method of the finishing liquid comprises the following steps of: adding 1, 3, 5-triacryloyl-hexahydro-1, 3, 5-triazine FAP (Fibroblast Activation Protein) and alkali into water according to the mass ratio of (50-160):(2-50), and heating to 80-95 DEG C, so as to carry out hydrolysis reaction on FAP till FAP is completely dissolved. According to the method, the problem of poor water solubility is overcome; the ammonia water modification disadvantage is also avoided; the effects of finishing, non-ironing and resisting crease of cotton fabrics by hydrolyzing FAP are good; because the purified cotton textiles are crosslinked under alkali conditions, the high-temperature acid degradation of cellulose is avoided; and the strength retention is high.

Description

technical field [0001] The invention belongs to the field of non-ironing finishing, and in particular relates to a non-ironing finishing method of high-strength retained pure cotton textiles. Background technique [0002] Cotton textiles are a common textile that is widely welcomed for its good comfort. However, pure cotton textiles are prone to wrinkling, especially after washing, which will affect the appearance and require ironing to achieve a smooth appearance. Non-iron anti-wrinkle finishing has emerged as the times require. At present, a mature 2D resin non-iron anti-wrinkle finishing technology has been formed, which can obtain a good appearance. 2D resin is an N-methylol finishing agent. Although the anti-wrinkle effect is good, 2D resin needs to use high-temperature baking under acidic conditions when finishing fabrics. Cellulose fibers will degrade under acidic and high-temperature conditions, causing great damage to fabrics. Poor abrasion resistance when worn. ...
